I just checked line 2285 in the code and it references the exact commit
were avps changed to xavps.
I would definitely try 5.1 and open an issue in github.
Can you post your relevant config related to this in case something is just
wrong there? (Both the request and failed route parts)

Hi
I think dispatcher changed from avps vars to xavps vars in master (5.2).
Can you try on latest stable (5.1) using avps instead just in case...?
Also, can you print in the logs the xavp_avp var you set in the modparam?

An example could be like this
3 nodes (A, B, C)
INVITE 1 -> ds_select_dst() -> Node A
INVITE 2 -> ds_select_dst() -> Node A
A dies
B replaced
C replaced
- external calls dispatcher.reload with new node list A (yes, died
state), E, F
INVITE 1 -> failure_route, ds_mark_dst() as Disabled
but with ds_next_dst() does not know anything about E or F, and B and C
already out of order.
So, my solution is again call ds_select_dst() in failure_route, but it
can return Node A (which is dead and I know it already). So, I’m trying to
select next node, with ds_next_dst() to select Node E, but calling this
command gives me
WARNING: dispatcher [dispatch.c:2285]: ds_update_dst(): no xavp uri field

If it brings the failed it’s because when it was marked as disabled that
node was already in the list, so it will fail and hit the failure route
again and move to next node.
The next call of ds_select_dst (in request route) will populate a list
without disabled nodes, etc.
To summarize:
- In request route call ds_select_dst()
- if it fails, in failed_route call ds_mark_dst() and then ds_next_dst()
Example:
...to keep it easy to understand, let's pretend that dispatcher doesn't
load balance and just failsover, let's say you have a ds group of nodes A,
B and C...
- INVITE 1 received. ds_select_dst() (the list contains A, B, C). $du=A
- INVITE 2 received. ds_select_dst() (the list contains A, B, C). $du=A
- A dies.
- INVITE 1 in failure route, A is maked as disabled, ds_next_dst()
(updated list contains B and C). $du=B
- INVITE 3 received, ds_select_dst() (the list contains B, C). $du=B
- INVITE 2 in failure route, A is already marked as disabled, ds_next_dst()
(updated list contains B and C). $du=B
- ...people talk via server B because A failed...
So really you would only send calls that populated the dispather list
before dying, after that the next calls wouldn't even try to hit that
server.
Can you give some more details on what kind of failover you are trying to
achieve?
Joel.

Hi!
I’ve used
ds_select_dst() and ds_next_dst() one after another in failure route.
If use in request/failure it’s working ok.
But again, during the failover in my environment dispatcher list can
change. And I don’t want to rely on ds_next_dst() cause it can bring me
absent node.
So, I’ve been thinking of use xavp variable to get data from it, but
still can’t get it to work.

I think you are confused between:
ds_select_dst() = get a node from the dispatcher group based on weight
and priority. Use in request_route.
ds_next_dst() = get the next node from the list previously created with
ds_select_dst(). Use this in failure_route.
Give it a try and let us know.

Is there any way to select not first destination
from ds_select_dst()?
Could not find any way to do this...

Sorry, hit sent too soon.
I meant ds_next_dst() or ds_next_domain():
